This new core security layer provides a unified data access path for all Hadoop ecosystem components, while improving performance.

We’re thrilled to announce the beta availability of RecordService, a distributed, scalable, data access service for unified access control and enforcement in Apache Hadoop. RecordService is Apache Licensed open source that we intend to transition to the Apache Software Foundation. In this post, we’ll explain the motivation, system architecture,

Security architecture is complex, but these testing strategies help Cloudera customers rely on production-ready results.

Among other things, good security requires user authentication and that authenticated users and services be granted access to those things (and only those things) that they’re authorized to use. Across Apache Hadoop and Apache Solr (which ships in CDH and powers Cloudera Search), authentication is accomplished using Kerberos and SPNego over HTTP and authorization is accomplished using Apache Sentry (the emerging standard for role-based fine grain access control,

Starting in CDH 5.3, Apache Sentry integration with HDFS saves admins a lot of work by centralizing access control permissions across components that utilize HDFS.

It’s been more than a year and a half since a couple of my colleagues here at Cloudera shipped the first version of Sentry (now Apache Sentry (incubating)). This project filled a huge security gap in the Apache Hadoop ecosystem by bringing truly secure and dependable fine grained authorization to the Hadoop ecosystem and provided out-of-the-box integration for Apache Hive.
